Method and apparatus of position tracking and detection of user input information

摘要

A method and apparatus of detecting user initiated movement by an input element handled by a user is disclosed. The method may include performing a calibration procedure that is initiated by the user via a physical movement performed by the user. The method may also include positioning at least one sensor to dynamically adjust a size of an effective workspace range capable of detecting the user's movement of the input element.

主权项

1. An apparatus, comprising:
a calibration input unit configured to perform a calibration procedure that is initiated by a physical movement performed by a user; and at least one sensor capable of detecting the user's movement of an input element; wherein the calibration input unit comprises a button that is disposed on a rigid arm and is moveable by movement of the rigid arm from a stored position within a housing of the sensor to an outward position at a known position relative to the sensor, wherein the button is coupled to the at least one sensor and is selectable by the user using the input element; wherein selection of the button by the input element establishes a position of the input element at the button relative to the sensor; and wherein the calibration input unit is configured to perform the calibration procedure by comparing a known position of the button relative to the sensor with a sensed position of the button as detected by the input element being placed on the button.
